Small Classification: Power Management (PMIC) - Voltage Reference. Base Product Number: ADR434. Series: XFET.

Key Features

Fixed 4.096 V precision output

Low noise, low drift XFET design

High initial accuracy with multiple grade options (family variants)

Tight line and load regulation

Wide supply range with headroom above 4.096 V (check datasheet for exact limits)

Supports industrial temperature operation (grade dependent)

Stable with recommended bypass/output capacitors

Simple 8-SOIC footprint, easy integration

RoHS-compliant, lead-free variants available

Key Advantages

Better measurement accuracy and repeatability for ADC/DAC references

Minimal temperature drift for long-term stability

Lower noise improves SNR in high-resolution converters

Reduces external calibration effort

Robust performance over supply and load changes

Straightforward design-in with standard SOIC packaging

Packaging

Type: 8-SOIC, narrow body, surface-mount

Material: Molded epoxy plastic body; tin-plated copper leads; JEDEC-standard outline

Size: body width 3.90 mm (0.154"), typical body length ~4.90 mm, thickness ~1.5 mm; lead pitch 1.27 mm; 8 leads total

Supplier Device Package: 8-SOIC (0.154", 3.90 mm width)

Mounting Type: Surface Mount

Packaging method: Tube

Pin configuration: 8-pin device; typical pins include VIN (supply), VOUT (reference output), GND, and TRIM/NR (if present), plus NC pins. See datasheet for exact pin assignments and recommended connections.

Thermal characteristics: small-outline package with typical ThetaJA in the ~120–160 °C/W range on a standard PCB; improve heat spreading with good copper area at GND; keep junction temperature within specified limits.

Electrical properties: 4.096 V nominal output; very low noise (sub-10 µV p‑p class in 0.1–10 Hz band); tight line/load regulation; low temperature coefficient (ppm/°C class); low quiescent current (sub‑mA range); designed to drive precision ADC/DAC reference inputs; stable with recommended input/output capacitors.

Lifecycle

Status: Active and widely available. Not nearing discontinuation based on current ADI portfolio visibility.

Family/package variants: ADR434ARZ, ADR434BR and similar grade/package options (accuracy and temperature specs vary by grade).

Equivalent or alternative models:

- Same family, different voltages: ADR430 (2.048 V), ADR431 (2.5 V), ADR432 (3.0 V), ADR433 (3.3 V), ADR435 (5.0 V)

- 4.096 V within ADI: LTC6655-4.096 (ultra‑low noise, high precision), LT6656-4.096 (low power, SOT‑23), ADR5044 (shunt 4.096 V, micropower)

- Cross-brand second source: REF5040 (Texas Instruments precision 4.096 V)
